Refractory armored quench ring

Abstract

An improved quench ring in combination with a reactor vessel having a refractory lined reaction chamber with a bottom outlet and a floor to support the refractory lined reaction chamber, wherein the quench ring is protected by a protective barrier comprising dense refractory brick, dense refractory ramming mix, refractory ceramic fiber, and a metal apron support. The protective barrier is removably attached to a portion of the quench ring hotface and protects the quench ring from the high temperature of the effluent exiting the reaction chamber.

1 . An improved quench ring in combination with a gasifier having a refractory lined reaction chamber with a bottom outlet and a floor to support said refractory lined reaction chamber, comprising: 
 (a) a quench ring for carrying a supply of cooling water therein and removably mounted beneath said floor;    (b) a protective thermal resistant barrier mounted contiguous to said quench ring; and    (c) said protective thermal resistant barrier abutted to the bottom outlet of the reaction chamber.    
     
     
         2 . The improved quench ring according to  claim 1 , wherein said protective thermal resistant barrier comprises a refractory barrier and an apron, wherein said apron is mounted adjacent to said quench ring, and wherein said refractory barrier is mounted between said apron and said bottom outlet.  
     
     
         3 . The improved quench ring according to  claim 2 , wherein said refractory barrier comprises dense refractory brick, dense refractory ramming mix, and refractory ceramic fiber.  
     
     
         4 . The improved quench ring according to  claim 2 , wherein said apron is removably affixed to said quench ring.  
     
     
         5 . The improved quench ring according to  claim 4 , wherein said apron comprises a cylindrical side wall which is mated to the quench ring hotface, an apron lip, and an apron floor which supports the refractory barrier.  
     
     
         6 . The improved quench ring according to  claim 2  wherein said refractory barrier is removably affixed to said apron and said bottom outlet.  
     
     
         7 . The improved quench ring according to  claim 5 , wherein said quench ring has a quench ring hotface which is perpendicular to the upper plate of the quench ring and which is removably affixed to the cylindrical side wall that extends from a bottom edge of said quench ring hotface.
